4.5 Description of functions

Note ... A more detailed description is available in the Description of parameters and objects.

The devices described here can, depending on the device type, be used either as presence and/or movement detector.

The difference between movement detector and presence detector:

The main application of the movement detector is the switching of light when persons are moving toward something. The main application of the presence detector serves for presence monitoring and makes it possible to switch lighting, heating or similar.

In a deactivated state the movement detector also switches without brightness. In an activated state it operates independent of the brightness.

Both movement detector and presence detector are based on the same detection principle. However, the detection segments of the presence detector have a finer mesh and can therefore also detect persons that are seated as being present and respond accordingly. In addition, a presence detector, different to the movement detector, can distinguish between artificial light (which has been activated by it) and natural light; this makes functions such as constant light control possible, for which the amount of artificial light is added to obtain a certain overall brightness.

Product description


Main applications:

• BW: Movement, detection range, detection of walking persons.

• PM: Also activities while seated.

The Busch-Presence detector KNX / Busch-Presence detector mini KNX is available in two versions:

» The standard version (6131/30-xxx-500 + 6131/20-xxx-500) offers movement detection with 2 channels, as well as constant light switching. Constant light switching adds light when persons move within the detection range and the daylight does not meet the required brightness level in the room. For this the device detects the luminosity of the lamps used. As soon as the natural light is adequate, the connected light sources are deactivated.

The combination of these two functions results in two advantages:

• Energy is being saved since the lamps are deactivated as soon as the natural light has reached sufficient brightness.

• Additional energy is saved since the lights are only switched on when persons are inside the room.

» The premium version (6131/31-xxx-500 + 6131/21-xxx-500) does not only switch lamps but can also dim them. This makes constant light control much more precise and maintains the brightness level in the room at the desired level. The integrated HVAC function makes it possible to control heating, ventilation and air-conditioning in the respective detection range when someone is present. This additionally saves energy. Two channels are available for this function. Special comfort is made possible with the integration of the IR remote control (6010/25-500). The device receives the signals and converts them on the KNX bus. The device also contains an integrated room temperature controller object with temperature sensor. In addition, the device has numerous general functions (see Description of parameters and objects).

Available also is the Busch-Watchdog Sky KNX. This device has the same functions as the standard version of the Busch-Presence detector KNX / Busch-Presence detector mini KNX. However, this device can be mounted in higher locations due to its greater sensitivity. It is better suited as movement detector.

Constant light Depending on the version, the devices offer various options to ensure that the brightness in the room is maintained at a more pleasant level. There is a difference between the functions of the constant light switch and the constant light controller. Both functions ensure that the brightness does not drop below a certain level when persons are in the room. The use of a presence detector is especially practical for work stations in an office, since even small movements are detected.

Product description


The constant light switch can switch lamps on and off. The constant light controller can additionally dim lights, to maintain a level that is as constant as possible. Both functions work in dependence of light conditions and movement in the detection range. The devices can operate either in "Automatic" or "Automatic switch-off" mode. If automatic switch-off is selected, for example, the light must be switched on manually via a control element. The light remains on as long as movement is detected and daylight is not sufficient. If no movement is detected, the switch-off delay expires. Only then is an OFF telegram sent to the bus via the output. In automatic mode the movement sensor also takes over the switch-on function as soon as someone enters the room.

» Constant light switch

The constant light switch switches on lamps in the room as soon as movement of a person is detected and the desired brightness value is not attained by the entering daylight alone. The programmed setpoint minus hysteresis is maintained as long as people are in the detection range. The application detects when the entering daylight is sufficient. The lamps are then switched off again to save energy.

Product description

[A] Artificial light curve

[B] Sunlight curve

Control parameters:

[1] Setpoint (lx)

[2] Delay time after switch-on up to measurement of the artificial light component

[3] Minimum time above the switch-off threshold (minutes)

To set up a constant light switch function certain parameters settings must be made which lead to dependencies. These dependencies are displayed in the above diagram. A switch-off delay can be set. This time expires when the presence detector no longer senses movement. After expiry, an OFF telegram is sent on the output. Connected lamps are switched off. The switch-off delay should always be higher than the "Delay after switch-on up to measurement of the artificial light component" (2). In the worst case the light sensor would measure the artificial light component when the lamps are switched off. This should be avoided since the entire constant light switching function is based on this value. The "Delay after switch-on up to measurement of the artificial light component" (2) is to be used especially with lamps that take a few seconds to reach their full brightness. Fluorescent lamps require up to around 250 seconds, whereas incandescent lamps reach their full brightness almost immediately. The "Minimum time above the switch-off threshold" (3) ensures that the natural light component attains a stable value before the artificial light is switched off. If this time is too short, this could lead to an unwanted activation and deactivation of the lamps in the room.

Note: Also the hysteresis must be taken into account. However, this is not displayed for reasons of simplicity.

Here the special parameter settings for 2 light rows must be observed.

» Constant light controller

In contrast to the constant light switch, there is the possibility of switching in several stages. Both the constant light controller and the constant light switch ensure that the level of brightness in the room does not drop below the desired level. However, the brightness controller is additionally able to send telegrams for dimming lamps to the KNX bus. This enables a constant level to be attained due to the dimming of lights brighter and darker, always in dependence of the natural light in the room. And the accuracy of the control increases with the operating time. The constant light controller remembers the luminosity of the lamps used, it measures this continuously (see also chapter 7.2.6, 'Information on calibrating the internal light controller). That is why the lights used later must also be used during commissioning of the presence detector with the constant light controller function. The artificial light component relative to daylight is also determined during commissioning. Next to the brightness the constant light controller also responds to the presence of persons in the room. This function can also be operated with 2 light rows.

4.6 Detection range

Note ... The mounting instructions contain the explanations for the detection ranges specific to the devices.

The detection range of the KNX presence detector depends on the movement of persons and the mounting height in the room. The movement sensor detects the smallest of movements, e.g. at PC work stations, at desks, etc. Here it must be distinguished between the inner and outer detection range and the mounting height of the presence detector.

» Inner detection range (seated persons)

Seated persons must be completely within the detection range. The shorter the distance between the person to be detected and the presence detector, the smaller the movement can be that is still detected. The reference level for the detection of seated activities is approx. 0.8 m. At this height, the detection range, such as for the Busch-Presence detector mini KNX is 6.5 m in diameter (mounting height of the presence detector = 3 m). At a higher mounting height, the detection range becomes larger, but the precision of detection gets smaller.

Product description


» Outer detection range (walking persons)

For the detection of walking persons, a larger detection range is available. The reference level for detection is the floor. A mounting height of 3 m results, as example for the Busch-Presence detector mini KNX, in a diameter of approx. 8 m for the detection range.

Fig. 6 Outer detection range

Note ... Limited detection The detection range of the presence detector can be restricted. The device does not need to be covered mechanically for this. Individual sectors can be deactivated in the application.

6.3 Sources of interference

The presence detector detects the movement of heat sources. If a foreign heat source is in close proximity, this can cause false triggering. Here a distinction must be made between foreign heat sources and limited visibility as a source of interference.

Limited view of the device The detection range of the device may be obstructed by various objects, e.g.:

- Lamp strip that have been installed lower than the device.

- Large plants

- Partitions

- Glass panes

Foreign heat sources Rapid changes in temperature surrounding the device can also trigger unwanted switching, E.g.:

- Additional fan

- Switching on/off of lamps in the direct vicinity (< 1.5 m) of the device, in particular incandescent lamps and halogen lamps

- Moving machines, printers, etc.

Heat sources without interference effect If the temperature changes only slowly, this will not affect the switching behaviour of the device, e.g. on:

- Radiators (distance > 1.5 m)

- Surfaces heated by the sun

- EDP systems (computers, monitors)

- Ventilation systems, when warm air does not flow directly into the device

7.2.6 Instructions on the calibration of the internal light controller

To commission the presence detector with a constant light function you have various parameters available in the ETS. These parameters allow numerous options for setting, in order to adapt the working mode of the device to individual requirements and circumstances. Therefore, the type of furniture, floor coverings or sources of interference in the room is of significance. The value to be set in a room with dark furniture will be less than in a room with a light-coloured floor and light-coloured furniture. Also the effect of the size of the interference, such as heat sources or short-term changes in brightness, such as passing clouds, can be taken into consideration.

For an optimum function of the constant light control a calibration of the sensor for the brightness detection is required. The following needs to be observed:

• The detection range of the sensor for brightness detection (see the following graphics; does not apply to the Busch-Watchdog Sky KNX).

• Reflection characteristics of the ground material within the detection range.

Fig. 15: Detection range of the sensor for brightness detection (does not apply to the Busch-Watchdog Sky KNX).

The sensor is calibrated via the respective software application. Observe the following applicable explanations.

There are two options for adjusting the brightness via the brightness detection application (see parameter "Correcting process fo internal brightness"):

Commissioning


» Use objects for brightness adjustment

There is the option of carrying out a brightness adjustment for daylight and artificial light via the brightness detection application with the aid of the following three objects:

(a) Brightness adjustment (daylight)

(b) Brightness adjustment (output 1)

(c) Brightness adjustment (output 2)

In the event that artificial light and daylight are perceived similarly by the sensor, or the movement detector application is used exclusively, only the absolute brightness value need be corrected. For this the brightness value can be sent via the brightness adjustment object (daylight), which is to be displayed by the actual brightness measured by the device. This is then used to internally calculate a correcting factor, which will then be used for scaling / adjusting the internally measured brightness. This adjustment is sufficient for the movement detector application. For constant light controller and switch further step may be necessary, which are described in the following.

For the event that daylight and artificial light must be corrected separately, the following procedure is recommended:

(a) Daylight adjustment - Carry out the measurement during sufficient daylight (> 1/2 * Setpoint) - Switch of the artificial light - Carry out the measurement of brightness at a defined location with a luxmeter - for example, lying down at the workplace with a view toward the ceiling - and wait until the light is close to being constant. Send the value to the device via the brightness adjustment (daylight) object. As little time as possible should pass between measuring and sending, to keep the probability of a change in light conditions at a minimum.

(b) Adjustment for channel 1

-- Darken the room - Switch on channel 1 (max. brightness) and wait until the brightness is virtually constant.

-- Measure the brightness with the luxmeter as previously. Send the value to the device via the "Brightness adjustment" object (output 1).

(c) Adjustment for channel 2

Repeat measurement (b) for channel 2. Switch off channel 1.

To complete the adjustment for the constant light controller, a further step is required during which the characteristic of the connected lamp is automatically measured in

dependence of the output value of the controller.

To be able to carry out the brightness calibration, the device must have been already programmed in such a way that aside from the "Start brightness calibration" object, also the output object(s) is/are connected with the corresponding actuators. Also the actuators should be programmed in such a way that the values received are set immediately, to ensure that the calibration process runs properly.

Here too, as in item (b), the room is to be darkened, to minimize the effect of changing daylight conditions during the measurement. If this is not possible, the adjustment should be carried out in the dark or at night. To obtain excellent results, the lamps should be turned on prior to the calibration. The calibration can start when the measured brightness is constant, i.e. the heat-up of the lamps has been completed.

The process of calibration now proceeds as follows:

1. Brightness calibration is started by sending a "1" to the Brightness calibration object (in the constant light application under extended parameters).

2. The lamps are switched on at 100%. Then comes a waiting period of 60 seconds for the lamps to warm up and reach their full brightness. Then the brightness is checked to see how much it has changed since the last measurement. If the change drops below a certain percentage in comparison to the measured value, it is assumed that the brightness is stable and the actual calibration can begin. Otherwise a new measurement is carried out after a certain time to again determine the percentage of change. This process is repeated until a stable brightness value has been reached. However, only up to a maximum of ten times.

3. Then the output values are reduced separately into steps of 10% and the corresponding brightness is determined for each value; and here, too, a waiting period is necessary until the brightness values have become stable:

• A1: 100% A2: 100%

• A1: 100% A2: 90%

• A1: 90% A2: 90%

• … …

• A1: 0% A2: 0%

4. After completion of the measurement the output characteristics are calculated and stored in the device. Then a successful measurement is confirmed in form of a "1" on the Start brightness calibration object.

5. If the calibration cannot be completed within a period of 6 minutes due to unfavourable light conditions (extremely fluctuating brightness values), the measurement is interrupted and a "0" is sent via the Start brightness calibration object.

Commissioning


Note ... The calibration can be terminated by sending a "0" via the "Start brightness calibration" object. The calibration is similar if only one output is used, but only with the A1 output values.

7.2.7 Additional comments

Setpoint

Note ... The following information is relevant only if no adjustment of brightness has been carried out.

Please note that the lux value to be set in the parameters does not correspond to the value required at the height of the desk. The light sensor is installed on the ceiling and can only measure the luminosity that is reflected from the opposite surfaces. The setpoint to be entered is therefore lower than the light value at the height of the work station. Dim the lights to the desired intensity. Then save the measured light value via the memory object of the presence detector. The stored value can also be read via the object for the setpoint.

Outputs

The presence detector can also regulate two independent light circuits per channel via the two outputs. The value of output 2 results from the value of output 1 and the respective proportionality factor. If the required setpoint is not reached, control continues beyond the factor.

For example:

An office is fitted with two light rows. Output 1 controls the light row in the darker part of the room. Light row 2 in the front window area is connected to output 2. For the maximum brightness during the day a proportional factor of 70% is sufficient for output 2. During the night the full brightness in the room is not sufficient for output 1 and output 2. Output 2 would now control beyond the proportional factor until the setpoint or the full brightness of the lamp has been reached.

Switch-off delay

The presence detector will switch off or dim the lamps in the room if no movement is detected. A switch-off delay can be set to prevent the lamp from being switched off immediately. This time starts as soon as movement is no longer detected. If movement is detected again within this period, the switch-off delay is reset.

Commissioning


Hysteresis

The hysteresis is a percentage value (+/-) that is related to the setpoint in lux. The hysteresis is a tolerance for maintaining the setpoint. The preset value is sufficient for most applications.

Operation


9 Operation

9.1 Operation via IR remote control

The premium version and the Busch-Watchdog Sky KNX have a sensor for receiving infrared signals. This allows the IR remote control 6010-25-500 to be used, for example.

Two channels that can be selected on the transmitter are available for operation: the blue and the white channel.

The following example is to serve as an aid for commissioning. The infrared functions can be programmed in the device. For button M1 (blue and / or white) the function "Switching, rocker switch left / right" is selected. The parameter "Reaction to rising edge" is shown within this function. This parameter is to be set on "ON". The function has the communication object "Switching". This object must now be connected with the object "Save setpoint" of the constant light application. This stores the current light value as setpoint as soon as button M1 is pressed. The light can, for example, be set with the remote control. For this, one or several button pairs are occupied with the function "Dimming rocker switch total" and connected directly with the dimming actuator. Now use the button pair selected to set the desired brightness and save the value with button M1.

11.3.9 General parameters - Switch-off delay (hh:mm:ss)

Options: 00:00:10 .. 00:05:00 .. 18:12:15

– The switch-off delay is the time period between the last movement detected and the sending of the telegram "Value for switch-off". If movement is detected again within this period, the switch-off delay timer is started again.

11.3.10 General parameters - Brightness-value threshold internal (lux)

Options: 1 .. 400 .. 1000

– The brightness-value threshold is used to specify the lux value at which the detector is to start to respond. If the detector does not switch on and the measured brightness lies above the set threshold, no telegram is sent during movement.

Options: No

Yes

– No: Only the most important parameters for setting the detector are displayed – Yes: All parameters are displayed, also those that are not required in most cases.

Examples: ■ Extended parameter settings ■ Status display parameter ■ Brightness parameter ■ External button parameter

11.3.13 Extended parameter settings - Operating mode

Options: Automatic mode

Automatic switch-off

Automatic switch-on

Monitoring

– Automatic = automatic switch-on and switch-off – Automatic switch-off = manual switch-on and automatic switch-off – Automatic switch-on = automatic switch-on and manual switch-off – Monitoring = automatic switch-on when there is sufficient movement within a specific time

period and automatic switch-off after a fixed switch-off delay of 2 seconds ■ Automatic: In "Automatic" mode the detector switches on automatically when detecting a

movement. The switch-off is effected after the set switch-off delay beginning from the most recent detection.



■ Automatic switch-off: In "Automatic switch-off" mode the detector must be switched on manually via object "External push-button (input)". The switch-off is effected automatically under consideration of the switch-off delay.

– Automatic switch-on: In "Automatic switch-on" mode the detector switches on automatically when detecting a movement. The switch-off is effected by the receipt of an Off telegram on object "External push-button (input)". Note: The detector switches off automatically after 6 hours.

■ Monitoring: In "Monitoring" mode the detector switches on brightness-dependent if an adjustable component of movement has been recorded within the time period set. The switch-off occurs 2 seconds after switch-on and the last detection of movement.

Note Manual switch-on and switch-off is possible in operating modes automatic, automatic switch-on and automatic switch-off via the external push-button (input). This external push-button is activated under the "External push-button" parameter. During manual switch-off the detection of movement is suppressed for the pause time. The purpose of pause time is to prevent an immediate re-activation. Example: The person switches the light off manually when leaving the room. Without the pause time the detected movement would cause a renewed switch-on during exiting.

11.3.14 Extended parameter settings - Use of a two-stage switch-off

Note This parameter is only displayed when "Output is of type" is set on 1 byte 0 - 100% or 1 byte 0 - 255.

Options: No

Yes

– No: The detector has a switch-off delay and, following the switch-off delay, transmits what has been set under the "Value for switch-off" parameter.

– Yes: After the switch-off delay the detector first switches to the set reduced brightness and only then sends the value set under the "Value for switch-off" parameter after brightness reduced according to switch-off delay.

Example: Switch-off delay = 5 minutes ■ Value for switching off = 0% ■ Value for reduced brightness = 20% ■ Brightness reduced according to switch-off delay = 3 minutes

If movement is now no longer detected, the light is dimmed to 20% after 5 minutes and then to 0% after a further 3 minutes (switch-off).



11.3.15 Extended parameter settings - Value for reduced brightness (%)

Options: 0 .. 20 .. 100

– Here the value for the reduced brightness is set. After the switch-off delay has expired the detector is to dimm the light to this value.

11.3.16 Extended parameter settings - Brightness reduced according to switch-off delay (hh:mm:ss)

Options: 00:00:10 .. 00:05:00 .. 18:12:15

– Here the value for the switch-off delay of the reduced brightness is set. The total switch-off delay then consists of the switch-off delay + brightness reduced according to switch-off delay

11.3.17 Extended parameter settings - Use of forced switch-off

Options: No

Yes

– No: The detector does not switch off after a specific time to carry out a new brightness measurement

– Yes: The detector switches off once after 3x switch-off delay or at a minimum of 90 minutes or a maximum of 24 hours to carry out a new brightness measurement

If the presence detector is switched on, it operates independent of brightness. Problem: When movement is detected the light remains on even though the brightness may be sufficient. This effect can be prevented by activating this parameter.

11.3.18 Extended parameter settings - Use of object for switch-off delay

Options: No

Yes

– No: The only option available is to change the switch-off delay via the switch-off delay parameter setting

– Yes: There is a separate 2-byte switch-off delay object (input) for changing the switch-off delay of the detector. The time entered is in seconds. A switch-off delay of 4 minutes, for example, has a value of 240 seconds.

Note The values which can be sent are between 10 and 65535 seconds. If a value that is too small or too large is sent, the value is automatically adjusted to the limit value: ■ Value < 10 -> Value = 10 ■ Value > 65535-> Value = 65535



11.3.19 Extended parameter settings - Use of object for brightness reduced according to switch-off delay

Options: No

Yes

– No: The only option available is to change the switch-off delay via the "Brightness reduced according to switch-off delay" parameter setting.

– Yes: There is a separate 2-byte brightness reduced according to switch-off delay object (input) for changing the switch-off delay for the reduced brightness of the detector. The time entered is in seconds. A switch-off delay of 4 minutes, for example, has a value of 240 seconds.


11.3.20 Extended parameter settings - Use of object for test mode

Options: No

Yes

– No: There is no possibility to set the detector to test mode to test the detection range. – Yes: There is a separate 1-bit test mode activation object (input) for activating the test mode

with a 1. The function is reset again with the receipt of a 0 on this object or automatically after 10 minutes. During the test mode the LED functions as movement detection indicator.

11.3.21 Extended parameter settings - Use of the actuator status object

Options: No

Yes

– No: There is no separate actuator status object for connecting with the status of an actuator. – Yes: A 1-bit actuator status communication object (input) is being enabled. This connected

with the status of a switch actuator, for example. When this actuator is switched off via a central command, the detector is informed and is ready again for switch-on after the pause time.



11.3.22 Extended parameter settings - Use of the status manually on/off object

Note This parameter is displayed only when automatic switch-on/switch-off has been activated and/or when the external push-button has been activated.

Options: No

Yes

– No: The is no separate status manual on/off object for monitoring the status of the control. – Yes: A 1-bit status manual on/off communication object (output) is being enabled. This

object sends an On telegram when the movement detector is deactivated and only one manual operation is possible via the external push-button input. If this object sends an Off telegram, the movement detector switches back to automatic mode.

11.3.23 Extended parameter settings - Pause time (ss.fff)

Options: 00.100 .. 01,250 .. 59,999

– The set pause time is started after the detector has been switched off due to expiry of the switch-off delay or when a switch-off telegram is received on objects external push-button or actuator status.

If movement is detected during this time, the detector is not switched on immediately. The pause time is first extended by 7 seconds. If there is still movement after these 7 seconds, the detector switches back on.

If no movement is detected during the pause time, the detector is ready for activation again after the pause time.

This behaviour can, for example, be important when the lamp cools down drastically and is located within the detection range of the detector. Without a blockage there would be an unintentional switch-on. The purpose of pause time is to prevent an immediate re-activation.

Example:

The person switches the light off manually when leaving the room. Without the pause time the detected movement would cause a renewed switch-on during exiting.

Note ■ The external push-button object is activated under the "External push-button"

parameter. ■ The actuator status object is activated under the status display parameter.



11.3.24 Extended parameter settings — Overwriting settings during a download

Options: Yes

• External/internal brightness threshold

• Brightness correction (daylight), see "Brightness detection" application

11.3.25 Brightness parameter - Use of object for detection independent of brightness

Options: No

Yes

– No: There is no separate object for detection independent of brightness. – Yes: A 1-bit communication object for brightness-independent detection (input) is being

enabled. This object allows the detector to be switched independent of brightness.

11.3.26 Brightness parameter - Activating detection independent of brightness with

Options: On telegram

Off telegram

– On telegram: Detection independent of brightness is activated with a 1 telegram and deactivated with a 0 telegram.

– Off telegram: Detection independent of brightness is activated with a 0 telegram and deactivated with a 1 telegram.

11.3.27 Brightness parameter - Detection independent of brightness after bus voltage recovery

Options: No

Yes

■ No: Detection independent of brightness is deactivated after a bus voltage recovery, reprogramming or a reset.

■ Yes: Detection independent of brightness is activated after a bus voltage recovery, reprogramming or a reset.



11.3.28 Brightness parameter - Input Slave takes the brightness into consideration

Options: No

Yes

– No: Every ON telegram to the input slave object ensures that the detector is switched on or the switch-off delay is reset. This is independent of whether the actual brightness is below or above the brightness-value threshold.

– Yes: The detector is switched on or the switch-off delay is reset only when the actual brightness is below the brightness-value threshold.

11.3.29 Brightness parameter - Used brightness

Options: Brightness-independent

Only internal

Only external

Internal or external

– Brightness-independent: The detector functions independent of brightness and will switch during each movement.

– Only internal: The detector uses its own measured brightness and brightness-value threshold internally to decide whether to switch on during movement.

– Only external: A 2-byte external brightness (input) communication object is enabled. The detector uses this externally measured brightness and the external brightness-value threshold parameter (lux) to decide whether to switch on during movement.

– Internal or external: The detector is activated only when the internally measured brightness drops below the internal brightness-value threshold or the externally measured brightness drops below the external brightness-value threshold.

11.3.30 Brightness parameter - Use object for internal brightness-value threshold

Options: No

Yes

– No: There is no separate internal brightness-value threshold object. – Yes: A 2-byte internal brightness-value threshold communication object (input) is being

enabled. This can be used to change the switching threshold at which the detector is activated. The value is sent to this object in lux.

11.4.6 General parameters - Brightness-value threshold internal (lux)

Options: 1 .. 20 .. 1000

This is used to set the desired brightness of the room. Below this threshold - hysteresis the presence detector switched at movement. The presence detector switches off again when the measured brightness - artificial light component = brightness-value threshold + hysteresis.

Note The value entered here is smaller than the control value set in the room via the luxmeter. This depends on the calibration of the brightness sensor for brightness detection settings. When the brightness adjustment is used there, the desired brightness must be set here for the working area.

Example:

The brightness at the top of the desk is to be 500 lux. The presence detector, however, measures the required brightness at the position it is mounted( e.g. on the ceiling it only measures 20 lux). This means that there is a difference between the brightness of light at the desk and the ceiling.

If the object is now used for brightness adjustment (daylight) or the objects brightness adjustment (output 1 / 2), one can enter 500 lux here (after calibration of the brightness sensor).



11.4.7 General parameters - Hysteresis (%)

Options: 00:00:40 .. 00:04:00 .. 00:05:00

– Here the time is set for when the constant light switch starts to subtract the artificial light component. This time is determined from the lamps used. Some lamps require a lot of time to reach maximum brightness, e.g. fluorescent lamps.

11.4.18 Extended parameters - Minimum time above the switch-off threshold (hh:mm)

Options: 00:01 .. 00:04 .. 01:00

– To prevent the light from switching off immediately after switching on (when the outside brightness has increased), a minimum switch-on time can be entered here. When the outside brightness drops below the brightness-value threshold within this time period, the time is set back.

The constant light switch will function again automatically after this time period. The constant light switch can be set on automatic again with a 1 telegram. This also important for regulating and automatic switch-off independent of movement.

Options: 00:05 .. 01:00 .. 12:00

– Here the time is set for when the constant light switch switches again to automatic mode after a manual switch-off.

11.4.21 Extended parameters - Pause time (ss.fff)

Options: 00.100 .. 01,250 .. 59,999




This behaviour can, for example, be important when the lamp cools down drastically and is located within the detection range of the detector. Without a blockage there would be an unintentional switch-on. The purpose of pause time is to prevent an immediate re-activation. Example: The person switches the light off manually when leaving the room. Without the pause time the detected movement would cause a renewed switch-on during exiting.

Options: 1 byte 0 - 100%

1 Byte (0 - 255)

– 1 Byte 0 - 100%: For activating dimmers. – 1 Byte 0 - 255: For actuators, which are activated with a value of between 0 and 255.

Note If the type of output is changed, also the options for setting the parameters change: ■ Bottom limit output 1 ■ Upper limit output 1 ■ Control starts at ■ Value for switching off In this manual only values for the 1-byte 0 - 100% setting are described.

11.5.2 General parameters - Bottom limit output 1 (%)

Options: 0 .. 100

– Here the bottom control limit is specified and up to which minimum value a dimmer is controlled.

11.5.3 General parameters - Upper limit output 1 (%)

Options: 0 .. 100

– Here the upper control limit is specified and up to which maximum value a dimmer is controlled.

11.5.4 General parameters - Control starts at (%)

– Here the value is specified at which the control starts and the lighting is switched on.



11.5.5 General parameters - Control speed (mm:ss)

Options: 02:30 .. 10:00 .. 20:00

– Here the time is specified which the control requires to get from 0 to the upper limit output value. Example: If the control speed is on 10:00 and the lighting is switched on with 50% and the upper limit is 100%, the control requires 5 minutes to get from 50% to 100%. Vice versa, the control requires 10 minutes to regulate from 100% to 0%.

11.5.6 General parameters - Setpoint brightness (lux)

Options: 1 .. 400 .. 1000

– Here the desired brightness of the room is to be set. Below this threshold - hysteresis the presence detector starts the control and starts to adjust the light until the setpoint has been reached again. The presence detector will not switch off but regulate against the bottom control limit. A switch-off takes place only when the limit = 0 or the switch-off delay has expired.

Note For a well-functioning constant light controller it is absolutely essential to calibrate the brightness sensors. The calibration is carried out via the brightness detection parameter. Here it is to be noted that the presence detector does not measure the brightness of the luxmeter on the working area (table), but the reflected brightness, which can, depending on the reflecting area, can be lower. Procedure:

• Switch of the artificial light/shield out the daylight • Send the value measured with the luxmeter via the object Similar procedure for daylight

Example:

The brightness at the top of the desk is to be 500 lux. The presence detector, however, measures the required brightness at the position it is mounted( e.g. on the ceiling it only measures 20 lux). This means that there is a difference between the brightness of light at the desk and the ceiling. If the object is now used for brightness adjustment, one can (after calibration of the brightness sensor) enter 500 lux here.

11.5.7 General parameters - Hysteresis (%)

Options: 10 .. 12 .. 100

– Switching threshold = setpoint ± hysteresis

The hysteresis prevents excessive switching when the current ambient brightness is close to the brightness threshold.




Options: 00:00:10 .. 00:05:00 .. 18:12:15

– The switch-off delay is the time period between the last movement detected and the sending of the telegram "Value for switch-off". If movement is detected again within this period, the switch-off delay is reset to the set value.

11.5.9 General parameters - Value for switch-off (%)

Options: 0 .. 100

– If movement is now no longer detected and the switch-off delay has expired, the value is sent via the bus.

Light controller (independent of movement)

– Automatic = automatic switch-on and switch-off. – Automatic switch-off = manual switch-on and automatic switch-off. – Light controller (independent of movement) = control dependent on brightness.

■ Automatic: In "Automatic" mode the presence detector switches on automatically when detecting movement. The switch-off is effected after the set switch-off delay beginning from the most recent detection.

■ Automatic switch-off: In "Automatic switch-off" mode the presence detector must be switched on manually via the switching (dimmer) object. The switch-off is effected automatically under consideration of the switch-off delay.

■ Light controller (independent of movement): In "Light controller" mode the presence detector only switches On or Off on the basis of brightness ± hysteresis. Activation/deactivation via the switching (dimmer) object.

11.5.13 Extended parameters - Use of a two-stage switch-off

Options: No

Yes

– No: The detector has a switch-off delay and, following the switch-off delay, transmits what has been set under the "Value for switch-off" parameter.

– Yes: After the switch-off delay the detector first switches to the set reduced brightness and only then sends the value set under the "Value for switch-off" parameter after brightness reduced according to switch-off delay.

Example: Switch-off delay = 5 minutes ■ Value for switching off = 0% ■ Value for reduced brightness = 20% ■ Brightness reduced according to switch-off delay = 3 minutes

If movement is now no longer detected, the light is dimmed to 20% after 5 minutes and then to 0% after a further 3 minutes (switch-off).

11.5.14 Extended parameters - Value for reduced brightness (%)

Options: 0 .. 20 .. 100

– Here the intermediate stage value where the detector is to control the light after the switch-off delay has expired.

– Here the value for the reduced brightness is set. After the switch-off delay has expired the detector is to dimm the light to this value.

Switch-off value ≤ bottom control limit ≤ reduced brightness < upper control or dimming limit.

Options: No

Yes

– No: There is only output 1, which sends its telegrams to an actuator. – Yes: An output 2 communication object (output) is being enabled. The constant light

controller now regulates the brightness with two outputs (while the second output is used proportional to the first out) in dependence of brightness. If the measured brightness is less than the setpoint, the value of the first output is increased up to the upper limit of output 1. During this control phase the second output is controlled proportional. If the setpoint still has not been reached, the value of the second output is increased up to the upper limit of output 2.

If the measured brightness is higher than the setpoint, the value of the second output is reduced first up the upper limit of output 1 x proportional factor. If the setpoint still has not been reached, output 1 is lowered up to reaching the lower limit of output 1. During this control phase the second output is controlled proportional. The bottom value of the second output is limited by the lower limit output 2 parameter. When appropriately parameterized the constant light controller can also switch off the associated dimming actuator.

11.5.21 Extended parameters - Proportionality factor output 2 to output 1 (%)

Options: 0 .. 100

– Here it is specified how output 2 behaves proportional in comparison to output 1.

For example:

If a factor of 20% is set here, output 2 will always be 20% behind output 1 or when output 1 is dimmed to 30%, output 2 will be dimmed to 10%. Only when output 1 is on its maximum value and the setpoint has not been reached, output 2 will leave this factor and dim higher until output 2 has also reached its maximum value.

11.8.2 General - Control function

Options: Heating

Heating with additional stage

Cooling

Cooling with additional stage

Heating and cooling

Heating and cooling with additional stages

– Heating: For operating a heat-based automatic single-room control. The temperature is regulated to the setpoint value defined in the parameter. The "Controller type" and "Heating type" can be programmed for optimal control.

– Heating with additional stage: In addition to the control function described under heating, the additional stage enables the activation of an additional heating circuit. This type of additional stage is used, for example, to quickly heat up a bathroom with floor heating via a heated towel rack.

– Cooling: For operating a cooling-based automatic single-room control. The temperature is regulated to the setpoint value defined in the parameter. The "Controller type" and "Cooling type" can be programmed for optimal control.

– Cooling with additional stage: In addition to the control function described under cooling, the additional stage enables the activation of an additional cooling device. This type of additional stage is used, for example, to quickly cool a room via an added cooling device.

– Heating and cooling: For operating a two-wire or four-wire system used to heat or cool a room. Switching between heating and cooling takes place using a central switch (two-wire system) or is carried out manually and / or automatically via the single room thermostat (four-wire system).



Heating and cooling with an additional stage: In addition to the heating and cooling functions, one additional stage each with an autonomous controller type can be programmed.

Note This parameter is only available if the "Device function" parameter is set on "Single device" or "Master device".

11.8.3 General - Operating mode after reset

Options: Comfort

Standby

Eco mode

Cooling with additional stage


After a reset the device will run in the operating mode after a restart until a new operating mode is set as the result of device operation or by communication objects, as the case may be. This operating mode should be defined during the planning phase. An improperly defined operating mode can result in a loss of comfort or increased energy consumption.

– Comfort: If the room temperature is not automatically lowered and the room is therefore controlled independent of its use.

– Standby: If the room is controlled automatically, e.g. by a presence detector, as a function of its use.

– Eco mode: If the room is controlled automatically or manually as a function of it use. – Frost/heat protection: If only the building protection function is necessary in the room after a

reset.

Note This parameter is only available if the "Device function" parameter is set on "Single device" or "Master device".

11.8.4 General - Additional functions

Options: No

Yes

– This parameter enables additional functions and communication objects, e.g. window contact and presence detector.



11.8.5 General - Send cyclic "In operation" (min)

Options: Setting option between 5 - 3000 minutes

– The "In operation" communication object serves to inform that the controller still operates. Value "1" is sent cyclic. This parameter is used to set the cycle for sending. If the cyclic telegram fails, the function of the device is faulty and the air-conditioning of the room can be maintained with a forced operation. However, for this the system and/or actuator must have "Forced operation" function.

Note This parameter is only available if the "Additional function" parameter is set to "Yes".

11.8.6 Heating control

Note Only available when the "Device function" parameter is set on either "Single device" or "Master device" and the control function parameter is set on either "Heating", "Heating with additional stage", "Heating and cooling" or "Heating and cooling with additional stages".

11.8.7 Heating control - Control value type

Options: 2-point 1 bit, Off/On

2-point 1 byte, (0/100%)

PI continuous, 0-100%

PI PWM, On/Off

Fan coil

The actuation of the control valve is determined by the selection of the controller type.

– 2-Point 1 Bit, Off/On: The 2-point control is the simplest type of control. The controller switches on when the room temperature drops below a certain level (setpoint temperature value minus hysteresis) and switches off when a particular value (setpoint temperature value plus hysteresis) is exceeded. The switch-on and switch-off commands are transmitted as 1-bit commands.

– 2-Point 1 Byte, 0/100%: This is another two-point control as described above. In this case, however, the switch-on and switch-off commands are transmitted as 1-byte values (0% / 100%).

– PI continuous, 0-100%: The PI controller adjusts its output value between 0% and 100% to match the difference between the actual value and the setpoint value and enables a precise regulation of the room temperature to the setpoint value. It sends the control value to the bus as a 1-byte value (0% - 100%). To reduce the bus load, the control value is only transmitted if it has changed by a predefined percentage in relation to the previous sent value. The control value can also be transmitted cyclically.

– PI PWM, On/Off: This also is a PI controller. Here, the output is a 1-bit command. For this to occur, the calculated control value is converted into a pulse-interval signal.



– Fan coil: The fan coil controller operates like the PI continuous controller. In addition, it allows the separate activation of the fan in the fan coil unit (e.g. fan speed levels 1 - 3).

11.8.8 Heating control - Heating type

Options: PI continuous, 0 – 100% and PI PWM, On/Off:

■ Area (e.g. floor heating) 4°C 200 min

■ Convector (e.g. heater) 1.5°C 100 min

■ Free configuration

Fan coil:

■ Fan coil 4°C 90 min


Multiple heating types (panel heating, convector heating or fan coil) with preset parameters are available to the user.

– If the required heating type is not available, individual parameters can be specified in free configuration.

Note This parameter is only available when "Control value type" parameter is set either on "PI continuous, 0 – 100%", "PI PWM, On/Off“ or "Fan coil".

11.8.9 Heating control - P-component (x 0.1°C)

Options: Setting option between 10 - 100

The P-component refers to the proportional band of a control. It fluctuates around the setpoint value and can be used to influence control speed with a PI controller. The smaller the set value, the faster it reacts to the control. However, to avoid the risk of an overshoot, this value should not be set too low. A P-component from 0.1 to 25.5 K can be set.

Note This parameter is only available when "Control value type" parameter is set either on "PI continuous, 0 – 100%", "PI PWM, On/Off“ or "Fan coil". In addition, the "Heating type" parameter must set on "Free configuration".



11.8.10 Heating control - I-component (min.)


The I-component refers to the reset time of a control. The integral component has the effect of moving the room temperature slowly toward, and ultimately reaching, the setpoint value. Depending on the type of system used, the reset time has to have different values. In general, the more inactive the overall system, the greater the reset time.

Note This parameter is only available when "Control value type" parameter is set either on "PI continuous, 0 – 100%", "PI PWM, On/Off“ or "Fan coil". In addition, the "Heating type" parameter must set on "Free configuration".

11.8.11 Heating control - Extended settings

Options: No

Yes

– This parameter enables additional functions and communication objects, e.g. "Basic stage heating".

11.8.12 Basic stage heating

Note Only available when the "Extended settings" parameter under "Heating control" is set on "Yes".

11.8.13 Basic stage heating - Status object heating

Options: No

Yes

– This parameter enables the "Status heating" communication object.

11.8.14 Basic stage heating - Mode of the control value

Options: Normal

Inverse

The mode of the control value can be used to adapt the control value to de-energised opened (normal) or de-energised closed (inverse) valves.

– Normal: Value 0 means "Valve closed". – Inverse: Value 0 means "Valve open".



11.8.15 Basic stage heating - Hysteresis (x 0.1°C)


The hysteresis of the two-point controller specifies the fluctuation range of the controller around the setpoint value. The lower switching point is located at "Setpoint value minus hysteresis" and the upper point is at "Setpoint value plus hysteresis".

Note This parameter is only available when the "Control value type" parameter is set either on "2-point 1 Bit, Off/On" or 2-point 1 Byte, 0/100%".

11.8.16 Basic stage heating - Control value difference for sending of heating control value

Options: 2 %

5 %

10 %

Send cyclic only

The control values of the 0 - 100% PI continuous controller are not transmitted after every calculation. Instead, they are transmitted when the calculation results in a value that is different enough to the previous sent value to make a transmission meaningful. This value difference can be entered here.


11.8.17 Basic stage heating - Cyclic sending of the control value (min)


The current control value used by the device can be cyclically transmitted to the bus.

Note This parameter is only available when the "Control value type" parameter is set either on "2-point 1 Byte, 0/100%", "PI continuous, 0-100%" or "Fan coil".



11.8.18 Basic stage heating - PWM cycle heating (min)


In PI PWM, On/off the control value percentage values are converted into a pulse-interval signal. This means that a selected PWM cycle will be divided into an on-phase and an off-phase based on the control value. Accordingly, a control value output of 33% in a PWM cycle of 15 min. results in an "On-phase" of five minutes and an "Off-phase" of 10 min. The time for a PWM cycle can be specified here.

Note This parameter is only available when the "Control value type" parameter is set on "PI PWM, On/Off“.

11.8.19 Basic stage heating - Maximum control value (0 - 255)


The maximum control value of the PI controller defines the maximum value outputted by the controller. If a maximum value under 255 is chosen, the value will not be exceeded, even if the controller calculates a higher control value.


11.8.20 Basic stage heating - Minimum control value for basic load (0 to 255)


The minimum control value of the PI controller defines the minimum value output by the controller. If a minimum value greater than zero is chosen, the controller will not output a lower value, even if it calculates a value that is lower. This parameter can be used to set a basic load, e.g. for operating floor heating. Even if the controller calculates the control value zero, a heating medium will flow through the floor heating system to prevent the floor from cooling down. Under "Settings of basic load", it is also possible to define whether this basic load will be permanently active or whether it will be switched by the "Basic load" object.


11.8.21 Control of additional heating stage

Note Only available when the "Device function" parameter is set on either "Single device" or "Master device" and the control function parameter is set on either "Heating with additional stage" or "Heating and cooling with additional stages".

Note This parameter is only available when "Control value type" parameter is set either on "PI continuous, 0 – 100%", "PI PWM, On/Off“ or "Fan coil". In addition, the "Additional heating type" parameter must set on "Free configuration".

11.8.25 Control of additional heating stage - P-component (min)



Note This parameter is only available when "Control value type" parameter is set either on "PI continuous, 0 – 100%", "PI PWM, On/Off“ or "Fan coil". In addition, the "Additional heating type" parameter must set on "Free configuration".



11.8.26 Control of additional heating stage - Temperature difference to basic stage (x 0.1°C)


The setpoint temperature of the additional stage is defined as a function of the current setpoint temperature of the base stage and is expressed as a difference. The value represents the setpoint value starting at which the additional stage will operate.

11.8.27 Control of additional heating stage - Extended settings

Options: No

Additional heating stage - Maximum control value (0 - 255)






11.8.33 Basic heating stage - Minimum control value for basic load (0 - 255)


The minimum control value of the PI controller defines the minimum value output by the controller. If a minimum value greater than zero is chosen, the controller will not output a lower value, even if it calculates a value that is lower. This parameter can be used to set a basic load, e.g. for operating floor heating. Even if the controller calculates the control value zero, a heating medium will flow through the floor heating system to prevent the floor from cooling down. Under "Settings of basic load", it is also possible to define whether this basic load will be permanently active or whether it will be switched by the "Basic load" object.


11.8.34 Cooling control

In PI PWM, On/off the control value percentage values are converted into a pulse-interval signal. This means that a selected PWM cycle will be divided into an on-phase and an off-phase based on the control value. Accordingly, a control value output of 33% in a PWM cycle of 15 min. results in an "On-phase" of five minutes and an "Off-phase" of 10 min. The time for a PWM cycle can be specified here.

11.8.88 Setpoint adjustment - Resetting the manual adjustment for change of operating mode

Options: No

Yes

If the device switches to a new operating mode, the manual adjustment is deleted and the parameterized setpoint temperature for the operating mode plus any change by the base setpoint value object will be applied if this parameter is activated. Example: Comfort temperature of 21°C plus manual adjustment of 1.5°C = 22.5°C. Change to Eco with programmed temperature 17°C. The device regulates the temperature to 17°C, since the manual adjustment is deleted.

If the parameter is deactivated, the manual setpoint adjustment will be added to the temperature in the new operating mode. Example: Comfort temperature of 21°C plus manual adjustment of 1.5°C = 22.5°C. If the system switches to Eco with a parameterized temperature of 17°C, the device regulates the temperature to 18.5°C, since the manual adjustment is added.

11.8.103 Alarm functions - Condensate water alarm

Options: No

Yes

If a fan coil is used, condensation may form during operation as a result of excessive cooling and/or humidity. The associated condensate is typically collected in a container. To protect the container against overflowing, and thus prevent potential damage to devices and/or the building, the container alerts the "Condensation alarm" object (receiving only) that the maximum fill level has been exceeded. This causes the controller to switch to a protective mode. This status is indicated by the corresponding icon on devices that have a display. Local operation is blocked. Operation is only possible again after the alarm has been deactivated.

Note This parameter is only available when the "Control function" parameter is set either on "Cooling", "Cooling with additional stage", "Heating and cooling" or "Heating and cooling with additional stages".



11.8.104 Alarm function — Dew point alarm

Options: No

Yes

When refrigerating machines are used, dew may appear on the refrigerant supply lines during operation as a result of excessive cooling and/or humidity. The dew indicator reports the dew formation via the "Dew point alarm" object (receiving only). This causes the controller to switch to a protective mode. This status is indicated by the corresponding icon on devices that have a display. Local operation is blocked. Operation is only possible again after the alarm has been deactivated.

Note This parameter is only available when the "Control function" parameter is set either on "Cooling", "Cooling with additional stage", "Heating and cooling" or "Heating and cooling with additional stages".

– 1 Bit m from n: The level values (0..3 or 0..5) are output using 1-bit objects. The number of objects available is the same as the number of fan speed levels. For level 2, for example, the 1-bit fan speed level objects 1 and 2 are output as the value 1, while the other fan speed level objects use the value 0.

– 1 Bit 1 from n: The level values (0..3 or 0..5) are output using 1-bit objects. The number of objects available is the same as the number of fan speed levels. For the level 2, for example, only the 1-bit fan speed level object 2 is output as the value 1. The other fan speed level objects use the value 0.

11.8.110 Fan coil settings - Fan speed levels - Level output

Options: For manual operation and automatic

Only for manual operation

This parameter is used to specify when the output of the fan speed level values will occur: either only when the fan speed levels are manually adjusted or also in automatic mode. This setting depends on the options for the fan coil actuator. If the actuator itself controls the fan speed levels in automatic mode based on a derivative of the control value, than the "Only for manual operation" option must be selected. Otherwise, the other option should be selected.

11.8.111 Fan coil settings - Fan speed levels - Lowest manually adjustable level

Options: Level 0

Level 1

This parameter is used to preselect the lowest fan speed level that can be set by an operation performed at the device. When level 0 is selected, the heating/cooling system will not be in operation (fan speed level and valve control 0) as long as the current operating mode and operation type are maintained. To avoid damage to the building, level 0 is deactivated after 18 hours and the device is returned to automatic mode.



11.8.112 Fan coil settings - Fan speed levels - Level status evaluation

Options: No

Yes

The controller obtains the current fan speed level for controlling a fan coil actuator either by calculating it from the table of level values under "Fan coil settings for heating" or "Fan coil settings for cooling", or by receiving feedback from the fan coil actuator.

11.8.114 Fan coil settings for heating - Speed level 1 to 5 up to control value (0 to 255) heating


In this parameter, the control values of the controller are assigned to fan speed levels. This assignment is used if the fan speed levels are transmitted together with the control values.

Note ■ These level settings should be adjusted to match the settings in the fan coil

actuator. ■ Setting the "Control value type" to "Fan coil" in the control parameters is only

useful for one of either the basic stage or the additional stage. Setting the basic and additional stage parameters to fan coil is not useful, since the control of only one fan coil actuator each for heating and cooling is supported.

■ The "Fan speed level 4 - 5 up to control value (0 - 255) heating“ parameters are available only when the "Number of fan speed levels" is set on "5 steps".

11.8.121 Summer compensation


11.8.122 Summer compensation - Summer compensation

Options: No

Yes

In order to save energy, and to ensure that the temperature difference occurring during entry and exit of a climate-controlled building stays within comfortable limits, the excessive reduction of room temperature should be prevented during high temperatures in the summer ( Summer compensation according to DIN 1946). The room temperature is increased by adjusting the setpoint temperature for cooling.

Raising the room temperature does not, however, mean that you heat up the room. Rather, the adjustment is intended to allow the room temperature to increase to a certain set value without cooling. This, for example, prevents the air-conditioning system from further reducing the room temperature to 24 °C with an outside temperature of 35°C.

However, activation of the summer compensation requires an outside temperature sensor that transmits its measured value to the bus and can be evaluated by the room temperature controller.

The following parameters are available for summer compensation: ■ "Lower outside temperature value for summer compensation", ■ "Upper outside temperature value for summer compensation", ■ “Lower setpoint offset for summer compensation", ■ “Upper setpoint offset for summer compensation"

Above the "Upper outside temperature value", the minimum setpoint temperature for cooling is the outside temperature minus the "Upper setpoint offset". The outside temperature has no effect on the minimum setpoint temperature for cooling below the "Lower outside temperature value". Between the "Lower" and "Upper outside temperature value", the minimum setpoint temperature for cooling undergoes floating adjustment by the parameterized setpoint temperature equal to the outside temperature minus the "Lower offset" to a value equal to the outside temperature minus the "Upper setpoint offset" as a function of the outside temperature.

Typical values for summer compensation are: ■ 21°C: lower outside temperature value ■ 32°C: upper outside temperature value ■ 0 K: lower setpoint offset ■ 6 K: upper setpoint offset

This means that a continuous increase of the minimum setpoint value for cooling occurs to a value equal to the outside temperature minus a setpoint offset of 0 to 6 K if the outside temperature increases to 32°C from 21°C.

For example:

For an increasing outside temperature, the minimum setpoint value for cooling will be increased



starting at an outside temperature of 21°C. The minimum setpoint temperature for cooling is 25.1°C at an outside temperature of 30°C; 25.5°C at an outside temperature of 31°C; 26°C at an outside temperature of 32°C; and 27°C at an outside temperature of 33°C.

The parameter is used to define how many degrees Kelvin the setpoint value will be increased by during summer compensation when the lower temperature value is reached.


That means that a flowing set value increase of 0 to 4 K occurs if the outside temperature increases from 20°C to 32°C.


11.8.125 Summer compensation - (Upper) exit temperature for summer compensation (°C)


The parameter defines the upper outside temperature value up to which temperature value the setpoint correction (summer compensation) is performed based on too high an outside temperature.




11.8.126 Summer compensation - Offset of the set-point temperature for the exit from summer compensation (x 0.1°C)


The parameter is used to define how many degrees Kelvin the setpoint value will be increased by during summer compensation when the upper temperature value is reached.


That means that a flowing set value increase of 0 to 4 K occurs if the outside temperature increases from 20°C to 32°C.

11.16.32 Outside temperature for summer compensation


30 Outside temperature for summer compensation

Input 2-byte floating point value

In order to save energy, and to ensure that the temperature difference occurring during entry and exit of a climate-controlled building stays within comfortable limits, the reduction of room temperature by cooling devices should be limited as a function of the outside temperature (summer compensation). This, for example, prevents the air-conditioning system from further reducing the room temperature to 24°C with an outside temperature of 35°C.

This function can only be used with an outside temperature sensor. This 2-byte communication object must then be used to provide the controller with the current outside temperature.



11.16.33 Summer compensation active


31 Summer compensation active Output Switching

This 1-bit communication object is used to indicate via the bus whether the summer compensation is active (1) or inactive (0). If it is active, the setpoint value configured for the cooling mode is increased by the summer compensation function. A decrease of the cooling mode setpoint temperature below the value calculated by the parameterized summer compensation function is not possible. An increase of the setpoint temperature for the cooling mode is always possible.

11.16.34 Set value reached


32 Set value reached Output Switching

When the setpoint set on the device in comfort mode has been reached it is sent by means of value (1) as information to the KNX bus via the 1-bit communication object. The function is started by activating the comfort or presence mode. If the reaching of the setpoint temperature is interfered with by the preselection of a different operating mode or by adjustment to a new setpoint, value (0) is sent.

11.16.35 Fahrenheit


33 1. Fahrenheit Input / output Switching

2. Fahrenheit (master) Input / output Switching

3. Fahrenheit (slave) Input / output Switching

The temperature indication on the display can be changed from Celsius (°C) to Fahrenheit (°F). The conversion from Celsius to Fahrenheit always takes place in the display unit, since only Celsius values are sent over the KNX bus. The value (0) results in a temperature indication in Celsius, while the value (1) results in Fahrenheit.

Note Item 2: If the Fahrenheit object is active in the master/slave mode, the Fahrenheit (slave) object must be connected to this object. Item 3: If the Fahrenheit object is active in the master/slave mode, the Fahrenheit (master) object must be connected to this object.



11.16.36 Display backlighting


34 Display backlighting Input / output Switching

The display backlighting is activated with value (1) and deactivated with value (0) via the 1-bit communication object.

Note This function is mainly used in rooms where backlighting during the night is considered to be a disturbing factor, such as in hotel rooms and bedrooms.

11.16.37 On/off request


35 1. On/off request (master) Input Switching

2. On/off request (slave) Input Switching
